Primes¶
- Calibration
- If the reference itself is flawed (a measurement standard that is actually biased), then perfect calibration to that reference produces systematically wrong outputs in absolute terms, a structural feature the Joint Committee for Guides in Metrology (JCGM, 2012) makes explicit in the International Vocabulary of Metrology (VIM).
This sourceBIPM. Defines measurement as comparison of a measurand to a reference quantity via a calibration chain anchored in a primary standard, making explicit the reference-dependence of calibration.

- Comparison
- Comparison is broader than measurement; measurement is comparison specialized to numerical output along a metric dimension, exactly the formal characterization the International Vocabulary of Metrology (JCGM 200:2012) gives by routing every measurement through a calibration chain anchored in a reference standard.
This sourceCharacterizes measurement as comparison of a measurand to a reference quantity via a calibration chain anchored in a primary standard — supports the claim that measurement is comparison specialized to numerical output along a metric dimension.

- Instrument Interpretive Drift
- The drift surfaces only through the frozen-reference method: re-measuring a certified master artefact — a gauge block whose true dimension cannot have changed — and reading the gap.
This sourceDefines metrological traceability and calibration against reference standards whose true value is fixed by construction, the basis of frozen-reference drift detection.

- Measurement
- In physics and engineering, the base units rest on a chain of procedures and reference artifacts, and metrology is the formalized discipline.
